Piezoelectric sensor



FIG. 1 is a perspective view of the front of a piezoelectric sensor;

FIG. 2 is a top plan view of the sensor of FIG. 1, the opposite bottom plan view being a mirror image of the top view;

FIG. 3 is a left side plan view of the sensor of FIG. 1, the opposite right side plan view being a mirror image of the left side;

FIG. 4 is a rear plan view of the sensor of FIG. 1, the front plan view being a mirror image of the rear;

FIG. 5 is a perspective view of the front of an alternative embodiment of a piezoelectric sensor;

FIG. 6 is a top plan view of the sensor of FIG. 5, the opposite bottom plan view being a mirror image of the top view;

FIG. 7 is a left side plan view of the sensor of FIG. 5, the opposite right side plan view being a mirror image of the left side; and,

FIG. 8 is a rear plan view of the sensor of FIG. 5, the front being a mirror image of the rear.

The broken lines in FIGS. 1–3 and 5–7 are intended to schematically represent a connector of any kind and form no part of the claimed design.
